Great shape!! 7K miles on the new motor. Phadt Coil Overs, Vara-Ram, MGW Short Shifter, Spec Stage 3+ Clutch, LME Built 403 Stroker, Long tube headers, Divider, Tuned by Mike Norris 444HP 441TQ. LME rates the motor at 1000HP able to take 22PSI. This has only been an NA motor and has never been stressed. Asking $25.5k open to trades but mostly aircraft related. I moved and it is getting old paying for storage.

My stock Z06 motor was going to need valves. The motor seemed like an appropriate solution. I originally had plans to through a YSI on there, but a new job and downsizing my toys got in the way.

If you were going to keep in NA, you could swap the heads for something smaller (AFR225 heads sell for a premium), bump up the compression, and change the cam to something more suited for NA and you would see LARGE HP gains. Should be over 500+RWHP NA. The blower cam is really holding it back as well as it not being able to fill the large heads with enough flow (NO FI). With this valvetrain, you could get something more peaky and make big power on top with a large fat torque curve.

A YSI with supporting mods would be 750+RWHP (+18PSI) from my research.

The coil overs are fantastic. While they were an expensive upgrade, it lowered the car to give it a fantastic stance (Alignment was adjusted for the lower stance), while still retaining a great, stock like ride. While firm it is not jarring or harsh. Then when its time to go on the track or more aggressive street driving, you can dial them down to downright firm for peak performance. It takes a few minutes and I haven't played with them much. I haven't taken it to any track days (Thanks to some of the guys on this forum I got hooked on Lemons racing), and my need for racing was fulfilled with crap can racing.
